+# Idasen
+
+Crate to control IDASEN standing desk from IKEA via Bluetooth.
+
+## Usage
+
+```rust
+use idasen::Idasen;
+
+// instantiate the struct, this will attempt to connect to the desk and discover its characteristics
+let desk = Idasen::new()?;
+
+// alternatively, if there's more than one desk you can get the correct one by it's mac addres
+// let desk = Idasen::by_addr("EC:86:F6:44:D3:31")?;
+
+// move desk up and down
+desk.up();
+desk.down();
+
+// stop desk from moving
+desk.stop();
+
+// move desk to desired position - minimum: 6200 (62cm), maximum: 12700 (1.27m)
+desk.move_to(7400);
+
+// get the position as an integer (10 = 1mm)
+println!("Position: {}", desk.position()?);
+```
